Re: Migrating ONTAP 8.3 to 9.5

I'd found the chart. Looks like my route is that I do need to upgrade my
8.3 cluster - possibly twice, if I want to do a more graceful update. (e.g.
take DR To 9.1, let it 'bed in' for a week, take prod to 9.1, push DR up to
9.4, etc.).

I might look to XCP/rsync as possibilities too, as that's "just" a
different kind of pain right now :).
